To a] Z wi l/077i 'IJMI/I/ concern.-

Be it known that I, RIcE OWEN CLARK, Jr. pipe manufacturer, a subject of His Majesty the King of the United Kingdom of Great Britain and Ireland, and aresident of Hobsonville, in the Provincial District of Auckland and. Colony of New Zealand, have invented a new and useful Machine for Flanging, Socketing, or Otherwise Shaping Earthenware Pipes and Material of a Similar Plastic Nature, of which the following is a specification.

The purpose of this machine is to do the Work of flanging, socketing, and otherwise shaping earthenware pipes and the like by machinery instead of by hand labor or molding, as is the case at present.

The machine consists, mainly, of a vertical shaft, which may be rotated or held station ary, having head-gear attached to and working on the shaft and various connections held to the head gear for operating crescentshaped flat roller or other form .of compress,- ors and side outer and. inner flange and other formation shapers.

The accompanying drawings show six iig ures, of which Figure 1 is a front elevation of machine as a whole, showing the different parts. Fig. 2 is a side elevation of the interlacing slides and retainers and shapers on the horizontal rods. Fig. 3 is a plan of the interlacing slides on the horizontal rods. Fig. 4 is a sectional view of the machine, showing the compressors or turn-over movement. Fig. 5 is a sectional view of the machine, showing the retainer and shaper movement; and Fig. 6 is a broken part showing the retainer and shaper with a cylindrical formation.

The vertical shaft A has three sets of headgear mountcd upon it, of which the headgear B works the outer cylinder segments or retainersC and the head-gear D works the i n ner cylinder segments or shapers or runnersup E. Both the outer retainers C and inner shapers E are mounted on two horizontalrods F, which are fitted. to and through a center block T fitted to under end of said vertical rod A, of which horizontal rods there are two others running at right angles and across the first-named rods. These other rods also have mounted on them similar outer retainers C. The rods G are connected to the outer retainers C at H and to the head gear B at l. The rods J are connected to the inner shapers or runners-up E at K and to the lower end of the head-gear D at L, which is projected therefrom by the vertical rods V.

The head gear M works the crescentshaped compressors or turn-overs N. The vertical arms 0 are attached to the head-gear M and are passed through slots or openings in head-gears D and B and the guide P to just below, from which diagonal jointed arms R pass downward and through diagonal slotted guides S, slidably fixed to slides on the rods F until they connect to the compressors N.

The three different sets of head-gears B, D, and M are movably fitted onto the vertical shaft A, so that upon their heads being gripped or held by clutches of levers or other forms of mechanism each set of head-gear can be separately set in motion and raised or lowered as required.

Horizontal slides U (shown in Figs. 2 and 8) can be used to work on and below the horizontal rods F. These horizontal slides U are shown separately in Figs. 2 and 3, so as not to complicate the drawings. They will be used in preference, though the outer retainers C and inner shapers E (shown in Figs. 1 and 3) can be used. without them. slide when being worked passes backward and forward beneath the portions of the cross-bars of the adjoining slide.

Though the outer retainers C and inner shapcrs E and turn-overs N, as shown on the drawings, are the shapes that will be used by preference, any formation having a surface which will give a sufficient point of contact can be used-such as flat surfaces, concave and convex surfaces, or cylinders which may be held stationary or revolve each on its own axis whether the machine as a whole is held stationary'or is made to rotate.

Projecting pieces can be provided for attachment to the outer retainers C and C or to the inner shapers E for giving a final finish to the tops of the pipes and will be projected between the retainers and shapers.

The machine as a whole may be held stationary or may be made to revolve by any suitable form of power. lVhere the machine is held stationary, the table beneath it 011 which the pipe to be worked is placed in a vertical position is made to rotate at such speed as may be requisite; but where the machine is caused to rotate or revolve the table and pipe are held stationary.

When putting the machine into use, the top edge of the pipe standing vertically upon the Each table beneath is brought so as to be beneath the compressors or turn-overs N when the head-gear which Works these turn-overs N will be caused by clutches, levers, or other mechanism to lower or drop the turn-overs N onto the top edge of the pipe, and in the rotation of either the pipe or the machine to press down and thicken the clay forming the top edge of the pipe until it fills the space between the retainers and shapers, when the turn-overs N are raised and the retainers C and shapers E are closed onto the pipe edge already lying between them by the headgears B and D, being caused by clutches, levers, or other mechanism to sufficiently draw in the outer retainers C and C and to sufficiently push out the inner shapers E, whereby the upper edge of the pipe already thickened isshaped by the rotation of either the pipe or the machine and the centrifugal force produced thereby into the flange shape wanted. WVhen this is done, the projecting pieces I/V will press onto the top edges of the flange and give it the final finish required, When the pipe is removed from the table and replaced by another flangeless pipe, which is treated in the same way as above described. In conducting the operation, water or any other suitable lubricant can be used to prevent the clay sticking to any of the parts of the machine it is brought in contact with.

W'herever slides are mentioned in this specification for any purpose, rollers suitably mounted and adjusted, or any other suitable formation which will give the motion necessary to produce the required working or operation to be carried out, can be used in place of the slides.

It is known that there are dumping-machines which flange small sizes of pipes on their sides only. The machine herein described and claimed for does its work vertically, which is preferable, and gives more satisfactory results than the side method of flanging, the work is done more easily, and any sized flange can be produced. Also friable and rotten clay which cannot be worked by other processes can be worked by this machine to advantage. The dumping-machines known have to dump the clay to thicken it, which is so severe an operation that only the strongest and best material can be used and only small pipes can be made.

Some of the advantages obtained by this machine are the greater speed with which the pipes canbe flanged, the neatness, strength, and uniform character of the article produced, the saving of manual labor, and the capacity of the machine to work and manipulate clay of a much more friable or rotten nature than can be done by any other process.

The rotation of this machine as a whole instead of the pipe being rotated, as is largely the practice with other processes in use at present, obviates the chances of the pipe breaking or flying to pieces by its own centrifugal force, that being a serious drawback with the present systems, as the pipe can with this machine be held stationary while the machine rotates, which operation shifts the centrifugal force to the machine.

Having fully described my invention, what I desire to claim and secure by Letters Patent is- 1. In combination, a retainer, a shaper, a compressor device, and independent mechanisms for causing the action of the same to form a flange on the pipe.

2. In a pipe-flanging machine, the combi nation of a vertical shaft, independent mechanisms slidably mounted thereon, compressors carried by a part of said mechanisms, and retainers and shapers cooperating therewith.

3. In a pipe-Hanging machine, the combination of a driving device, mechanism having compressors slidably mounted on said driving device, independent mechanisms having retainers and shapers slidable on the driving device and means for actuating said device.

4. A machine of the class described involving a rotary shaft having head-gears slidably mounted thereon, vertical rods carriedthereby, diagonal rods secured to the vertical rods, guides for said rods, means connected to the diagonal rods to form a flange on a pipe and means for imparting motion to the head-gears.

5. A machine involving a rotary vertical shaft having a plurality of head-gears slidably mounted thereon, series of rods carried by each of the head-gears, guides for the said rods, compressors secured to the free ends of one series of rods and retainers and shapers secured to another series of rods for the purpose described.

6. In a pipe-flanging machine, the combination of a vertical shaft having a headgear slidably mounted thereon, rods carried thereby having diagonal extensions, compressors supported on the ends of the extensions, a second head-gearslidable on said shaft, rods secured on said second head-gear and extended outwardly beyond the firstmentioned rods, retainers carried by said outwardly-extended rods, a further head gear slidably mounted on said shaft and having rods provided with shapers, means for guiding the rods and means for actuating the head-gears.
